Machinability

Improved Machinability Stainless Steel Bar for cost-efficient component manufacturing

Sandvik has taken the alloy a significant step forward by improving its machining properties.This is achieved through the addition of sulphur and by optimized inclusion morphology. As every member of the Sanmac family, Sanmac 316/316L is optimized for controlled chip breaking as well as secure and efficient machining, allowing for increased cutting speed, longer tool life and minimal operator engagement.

Improves your production economy

Sanmac® is the result of extensive efforts to improve the machinability of stainless steel grades and the design of tooling concepts suitable for stainless steel machining.The result of this cooperation between Sandvik Materials Technology and Sandvik Coromant is improved production economy for you as our customer.

Higher productivity

The family of Sanmac stainless steels has now been further improved through extensive product development to increase productivity for customers in the machining industry. With Sanmac we have been able to reduce tool wear, and increase cutting speeds, giving productivity improvements and therefore significant cost reductions per produced article.The Sanmac program is continuously being extended with new steel grades and dimensions.
